A Bent Crystal Neutron Spectrometer and Its Application to Neutron Cross-Section Measurements

Abstract
The high neutron fluxes now available as a result of the development of chain reacting piles has made it possible to obtain monoenergetic neutron beams of considerable intensity by the method of crystal diffraction. One of the first practical applications of this method has been in the study of neutron resonance cross sections for low energy neutrons.
